FIELD OF THE INVENTION

The present invention is concerned with an accessory module system for a vehicle window, in particular for housing a plurality of electronic accessories which can communicate with and/or through a windscreen of the vehicle. The system may also house accessories associated with, for example, the environmental control of the vehicle cabin, the communication of information to the driver/passenger by means of a digital display or the like, or a communications system such as a hands free phone. The system is also preferably adapted for the modular location of accessories therein, in order to allow variations in specification or luxury level.

BACKGROUND OF THE INVENTION

Certain accessories of a vehicle, such as a rain sensor assembly or imaging sensor assembly, typically are mounted tight against an interior surface of a windshield or window. This is required in some cases to maintain a desired distance between a light emitter/light sensor and the interior surface of the windshield, and/or to optically or thermally couple the component to the windshield, and/or to substantially seal the component at the windshield to prevent dust, dirt, smoke or other contaminants from affecting the component. However, as a result of this requirement, the accessory module assembly must be sufficiently rigid to apply and maintain a suitable force to the various components in order to maintain the components or accessories in intimate contact with the windscreen. As a result, the module assembly has little or no resilience, and is thus not generally capable of slight deformations to closely follow the contour of the windscreen.

It is also desired to provide a blacked out area or ceramic frit region in areas where such accessories are mounted at the windshield, in order to enhance the appearance of the vehicle. Therefore, an aperture or port may have to be formed in the frit layer for the camera or image sensor to be aligned with. However, the frit layer then may include the port or aperture even for vehicles where the camera-based or other accessory is not selected as an option. In order to provide an appropriate frit layer for the camera-based accessory option, the vehicle manufacturer may need to plan or design different frit layers for different options available to the vehicle, which may result in a proliferation of windshields and part numbers for the different optional accessories.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the accompanying drawings there is illustrated an accessory module system, generally indicated as 10, for mounting against a vehicle window (not shown) in particular a windscreen of a vehicle, as will be described in more detail hereinafter. The system 10 comprises an accessory module assembly 12 and, in the preferred embodiment illustrated, a mirror assembly 14 detachably connected to the module assembly 12 in substantially conventional fashion. It will however be appreciated from the following description that the mirror assembly 14 does not form an essential element of the invention, and the system 10 could be provided without the mirror assembly 14. The module assembly 12 could be designed to be seated against or partially surrounding an existing mirror assembly mounted directly to the vehicle windscreen. When included, the mirror assembly 14 may be of any conventional form, and preferably has a front opening (not shown) which is normally closed by a reflective element (also not shown). The reflective element may comprise an electro-optic cell (such as an electrochromic mirror element) so that the reflectivity of the mirror assembly 14 can be electrically varied according to prevailing conditions. The construction and operation of the mirror assembly 14 is well known to those skilled in the art, and no further details are therefore deemed necessary.

The accessory module assembly 12 comprises a frame assembly 16 containing, as will be described in detail hereinafter, a plurality of accessories in the form of electronic components for taking various measurements/readings and/or for controlling various functions of the vehicle to which the system 10 is fitted. The accessory module assembly 12 further comprises a cover assembly 18 detachably connected to the frame assembly 16, and located in use between the frame assembly 16 and the windscreen (not shown) of the vehicle. The cover assembly 18 performs a number of functions, primarily to shield from view the various components or accessories contained within the accessory module assembly 12, when viewed from an exterior of the vehicle. In addition, the cover assembly 18 closely conforms to the shape of the windscreen in order to provide an aesthetically pleasing fit between the accessory module assembly 12 and the windscreen, while also substantially preventing the ingress of contaminants between the windscreen and the cover assembly 18, which might otherwise adversely affect the operation of one or more of the accessories which communication with and/or through the windscreen. These functions, and others, will be described in greater detail hereinafter.

The accessory module assembly 12 may be mounted against the windscreen by any suitable means, for example using an adhesive or the like. However, in the preferred embodiment illustrated, the system 10 comprises an attachment member comprising three discrete fixing elements in the form of rails 20 which in use are mounted to the vehicle windscreen by an adhesive or the like. There could of course be more or less rails 20 if desired or required. The frame assembly 16 comprises a mounting portion in the form of three correspondingly positioned recesses 22 for receiving the rails 20, the frame assembly 16 and rails 20 preferably having co-operating retention means (not shown) such as clips or the like, in order to secure the frame assembly 16 to the rails 20, and therefore the vehicle windscreen. Alternatively a screw (not shown) or similar fastener element may be passed through the frame assembly 16 and into the respective rail 20. In order to simplify the process of fitting the rails 20 to the windscreen, and to eliminate the possibility of inaccurate spacing between each of the three rails 20, the rails 20 are preferably initially located within a frame or jig (not shown) which accurately positions the rails 20 with respect to one another. The frame or jig can then be positioned against the windscreen in order to simultaneously position each of the rails 20, at the correct positions, in contact with the windscreen, to be suitably secured in place, preferably by means of a suitable adhesive. Alternatively, the rails 20 could be formed integrally with such a frame or jig, which could then, with the rails 20 fixed to the windscreen, form a permanent sub-frame of the accessory module assembly 12. This arrangement greatly improves the tolerances achievable, while reducing the time and therefore cost of fitting the rails 20 to the windscreen. Further time and cost savings can then be expected when it comes to fitting the frame assembly 16 to the rails 20, as the elimination of inaccuracies in spacing between the rails 20 will ensure that the frames 16 consistently and accurately fit into position about the rails 20. It will also be apparent that any other fixing elements may be employed to allow the module assembly 12 to be secured against the vehicle windscreen.

On the cabin facing side of the accessory module assembly 12, there is provided an outer casing 24 surrounding the frame assembly 16 with a support bracket 26 projecting from the frame assembly 16, through the outer casing 24, to which the mirror assembly 14 is connected, preferably by a ball and socket joint or the like. As the rails 20 are all recessed inwardly of the frame assembly 16, and with the outer casing 24 in place, the accessory module assembly 12 is given a “floating” appearance from the vehicle interior. For ease of installation, the outer casing 24 is preferably provided in two parts, as illustrated in FIG. 4, allowing the two parts to be quickly and easily installed/removed on the module assembly 12. Any suitable means may be provided to secure the two parts together, in addition to securing the outer casing 24 to the module assembly 12.

Optionally, accessory module assembly 12 may be a stand-alone module assembly that is separate and distinct from the interior rearview mirror 13 of the vehicle (FIG. 7). If so, it may be desirable to include a mirror mounting button as part of accessory module assembly 12 so that an interior mirror assembly can be attached thereto in a “button-on-button” attachment manner such as is disclosed in the likes of U.S. Pat. Nos. 6,968,736; 6,824,281; and 6,690,268 (the entire disclosures of which are hereby incorporated by reference herein). In this regard, inclusion of a rain sensor (whether contacting or non-contacting such as a capacitive rain sensor being developed by Preh-Werke GmbH & Co. KG of Bad Neustadt, Germany) is contemplated.

Turning then to the interior of the accessory module assembly 12, and as mentioned above, a plurality of accessories or electronic components are housed therein, for performing various functions to and within the vehicle to improve the safety and/or comfort for the vehicle occupants. In the preferred embodiment illustrated, these accessories comprise a camera 28, a rain sensor assembly 30, a windscreen temperature sensor assembly 32, a closing velocity (CV) sensor assembly 34, and a compass 36, the configuration and operation of each of which is described in detail below. As will also be described hereinafter, the frame assembly 16 defines a site in the form of an enclosure 29 for the camera 28, a site in the form of a cradle 31 for the rain sensor assembly 30, a site in the form of a sleeve 33 for the temperature sensor assembly 32, and a site in the form of an opening 35 for the CV sensor assembly 34. Compass 36 preferably includes a compass sensor, such as a magneto-responsive sensor such as a magneto-resistive sensor, a magneto-capacitive sensor, a magneto-inductive sensor, a Hall effect sensor, or a flux gate sensor and/or a compass display, such as the types disclosed in U.S. Pat. No. 5,802,727, which is hereby incorporated herein by reference or in U.S. provisional application Ser. No. 60/636,931, filed Dec. 17, 2004, which is hereby incorporated herein by reference in its entirety.

All of the above accessories, except the compass 36, require either direct contact with the vehicle windscreen, or the ability to communicate, through the windscreen, with the exterior of the vehicle, for reasons set out hereinafter. Thus although the cover assembly 18 masks the internal workings of the accessory module assembly 12 from the exterior of the vehicle, the cover assembly 18 is nevertheless provided with a camera aperture 38 and associated channel 40, a rain sensor aperture 42, a windscreen temperature sensor aperture 44, a transmitter aperture 46 and associated channel 48, and a receiver aperture 50 and associated channel 52. These apertures in the cover assembly 18 allow the respective components to communicate with and/or through the windscreen.

Turning firstly to the camera 28, and referring to FIG. 5, a pair of tabs 54 are provided, one on either side of the camera 28, to facilitate connection of the camera 28 to the frame assembly 16. In the preferred embodiment illustrated, the site for the camera 28, in addition to the opening 29, comprises a pair of abutments 56 located on the frame assembly 16, to which abutments 56 the tabs 54 are secured by any suitable means, for example screws or the like. When mounted as illustrated, the line of vision of the camera 28 is directed through the camera aperture 38 in the cover assembly 18, along the corresponding channel 40, and in use out through the windscreen of the vehicle. The camera 28 may then be employed as part of a collision avoidance system for the vehicle, by focusing the camera a suitable distance beyond the bonnet of the vehicle, with feedback from the camera then being employed to generate warning signals, preferably audio and/or visual warning signals, if a collision seems imminent, or to actively intervene, for example by lightly applying the brakes of the vehicle, in an attempt to avoid any such collision. Such a collision avoidance system in isolation is known, for example as produced by Delphi Automotive Systems of Troy, Michigan, the United States.

Although in the embodiment illustrated the camera 28 is affixed to the frame assembly 16 via the tabs 54 and corresponding abutments 56, any other suitable mounting means may be employed. For example it is envisaged that connecting means (not shown) could be employed which provide the simultaneous mechanical and electrical connection of the camera 28 to the frame assembly 16. The same arrangement could be employed for the rain sensor assembly 30, window temperature sensor assembly 32 and the closing velocity sensor assembly 34. Such connecting means could for example employ magnetic elements to achieve both the mechanical and electrical connection of one or more of the accessories into the frame assembly 16. Such an arrangement is particularly advantageous where the accessory or associated connection point is in an awkward or out of sight location.

When the module assembly 12 is fitted to a vehicle, it is necessary to conduct a final alignment of the camera 28 relative to the exterior of the vehicle, in particular the front of the bonnet. This final alignment is however undertaken in a known manner using dedicated software, which does not therefore require the physical adjustment of the camera 28 within the module assembly 12. However, this final software effected alignment is capable of achieving only a small range of adjustment in the x, y and z directions. For this reason, it is desirable that the position of the camera 28 can be physically adjusted within the frame assembly 16. This adjustment is preferably achieved at the point of mounting the camera 28 to the frame assembly 16, and in the embodiment illustrated, via the tabs 54 and corresponding abutments 56, which may be suitably modified, although not illustrated, to allow the simple x, y and z axes adjustment of the camera 28 relative to the frame assembly 16. Alternatively, the adjustment may take the form of calibrating the camera 28 to the frame assembly 16 by, for example, the addition or removal of material such as shims or similar spacers (not shown) such as to achieve a combined tolerance for the camera 28 and frame assembly 16. It will of course be understood that any other suitable or equivalent arrangement could be employed to achieve this desired result. It will also be appreciated that similar provisions could be employed for any of the other accessories within the system 10.

Turning then to the rain sensor assembly 30, the frame assembly 16 is provided with the cradle 31 for receiving and retaining the rain sensor assembly 30. In order to function correctly, the rain sensor assembly 30 must be urged, in use, against the vehicle windscreen with significant force. Thus in use the rain sensor assembly 30 is pressed through the rain sensor aperture 42 in the cover assembly 18. As no adhesive or the like is to be utilized in securing the rain sensor assembly 30 to the windscreen, the force to be applied to the rain sensor assembly 30 must thus be applied by the frame assembly 16, via the cradle 31. For this reason it is preferable that the frame assembly 16, and therefore the cradle 31, is formed from a substantially rigid material, for example a metal, and in particular die-cast aluminum or an alloy thereof. The frame assembly 16 can then be mounted against the windscreen, the rigidity thereof ensuring that the frame assembly 16 is capable of applying, and maintaining, a suitable force to the rain sensor assembly 30 in order to urge same against the windscreen.

The windscreen temperature sensor assembly 32 is mounted within the sleeve 33 formed integrally with the frame assembly 16, with the free end of the windscreen temperature sensor assembly 32 projecting through the windscreen temperature sensor aperture 44 to contact and be urged against the interior surface of the vehicle windscreen. In this way, and as described in our co-pending International Patent Application No. PCT/EP2005/010071 (the entire disclosure of which is hereby incorporated by reference herein), the temperature sensor assembly 32 can be used in combination with additional sensor assemblies (not shown) to predict internal misting of the vehicle windshield, and take active steps to prevent such an occurrence, for example by activating an air conditioning system (not shown) of the vehicle. The temperature sensor assembly 32 may be spring biased within the sleeve 33, in order to ensure that an intimate thermally conductive contact is made between the temperature sensor assembly 32 and the windscreen.

The preferred closing velocity (CV) sensor assembly 34 utilizes a LIDAR (light detection and ranging) collision-avoidance detector which operates on a similar principle as radar. Basically, the CV sensor assembly 34 emits light, through the transmitter aperture 46 and associated channel 48, through the vehicle windscreen, and forwardly of the vehicle. The transmitted light will then be reflected by a leading vehicle if within a certain range, the reflected light being received by the CV sensor assembly 34, via the receiver aperture 50 and associated channel 52. The CV sensor assembly 34 can then determine the velocity and range of a leading vehicle, and again take preventative measures to avoid a collision. Again this type of system is already in existence in isolation, for example as manufactured by Continental Temick. To improve the performance/accuracy of the CV sensor assembly 34, it is desirable to substantially eliminate stray or background light being reflected onto the CV sensor 34 from the walls of the channel 52, as this may lead to false or inaccurate readings. It is therefore preferable that the walls of the channel 52 are coated or covered with a light absorbing layer or film, which may be in the form of a paint, fabric, or any other suitable coating.

In the preferred embodiment illustrated, the CV sensor assembly 34 is provided prefixed in a custom molded housing 58 which can then quickly and easily be located and secured within the opening 35 in the frame assembly 16. In order to secure the housing 58 relative to the frame assembly 16, the housing 58 is provided with a plurality of tabs 60, with the cover assembly 18 comprising a mounting member in the form of corresponding slots 62 for receiving the tabs 60. The housing 58, containing the CV sensor assembly 34, can then quickly and easily be clipped onto the underside of the cover assembly 18, ensuring accurate alignment of the CV sensor assembly 34 with the transmitting and receiving apertures 46, 50. Once the cover assembly 18 is mounted onto the frame assembly 16, the housing 58, and therefore the CV sensor assembly 34, are positioned within the dedicated opening 35 in the frame assembly 16. It will of course be appreciated that any other suitable arrangement may be employed in order to secure the housing 58 relative to the frame assembly 16. For example, the frame assembly 16 could be provided with means for receiving the tabs 60.

The compass 36, in the preferred embodiment illustrated, is provided on a printed circuit board (PCB) mounted on the support bracket 26, which thus acts as the site for the compass 36. It will of course be appreciated that the compass 36 could be located in any other suitable position within the accessory module assembly 12. The outer casing 24 is then provided with a window 37 formed therein, through which window 37 the compass 36 is visible from an interior of the vehicle. The window 37 could be enlarged to reveal a display from, or associated with, one or more additional accessories (not shown), for example an environmental control system (not shown) including, for example, a cabin temperature sensor assembly, a humidity sensor assembly, an exterior temperature sensor assembly, a petrol gauge, or any other useful display. The system 10 could also be adapted such that said enlarged display (not shown) could be provided as a separate add on module or component (not shown) which may be clipped or otherwise secured to the module assembly 12, preferably at or adjacent the site of the window 37, in order to be clearly visible to a vehicle occupant, above the mirror assembly 14.

In order to reduce the amount of wiring between a vehicle and the accessory module system 10, an electrical terminal 64 is provided within the accessory module assembly 12, and in the embodiment illustrated is adjacent the rain sensor assembly 30. The terminal 64 is connected to the vehicle via a single power and/or control cable, namely a first power/control input 66 which passes through the outer casing 24 as illustrated in FIG. 4, across the frame assembly 16, for connection with the terminal 64. Extending out of the terminal 64 is a first power/control outlet 68 which connects to the CV sensor assembly 34, a second power/control outlet 70 which connects to the rain sensor assembly 30, and a third power/control outlet 72 which extends into the mirror assembly 14, in order to power/control any electronic components contained therein. Thus in this way a plurality of the accessories contained within the accessory module system 10 may be powered/controlled from a single power/control input 66 provided to the accessory module assembly 12, thereby greatly reducing the wiring requirements between a vehicle and the accessory module system 10.

In the embodiment illustrated, the camera 28 employed utilizes complementary metal oxide semi-conductor (CMOS) circuitry and processing, and as a result requires a separate power/control supply to the remaining accessories within the accessory module system 10. Thus in the embodiment illustrated a second power/control input 74 is provided between the vehicle and the accessory module assembly 12, which again passes through the outer casing 24, and terminates in a plug 76. The camera 28 is provided with a complimentary plug 78 which connects to the plug 76 in order to provide power/control to the camera 28. Thus the accessory module system 10 requires only two wiring inputs in order to control a plurality of accessories. If the camera 28 were omitted from the accessory module system 10, only a single electrical connection would be required between the vehicle and the accessory module system 10. It will also be apparent that the terminal 64 could be modified to supply power/control to more than the three accessories provided in the preferred embodiment illustrated.

Indeed as the accessory module system 10, and in particular the accessory module assembly 12, is designed to be modular in nature, allowing the inclusion or omission of one or more of the accessories therein, without affecting the operation of the remaining accessories, the primary function of the terminal 64 is to allow a single incoming wiring configuration to be utilized with the accessory module system 10, regardless of the internal configuration of accessories contained within the accessory module assembly 12. If more or less accessories are utilized than in the preferred embodiment illustrated, the first power/control outlet 68, second outlet 70 and third outlet 72, which together form an internal wiring harness for the accessory module assembly 12, need simply be replaced with a suitably modified version of same in order to accommodate the array of accessories to be utilized.

Communication between the accessories within the accessory module assembly 12 and the vehicle systems to be controlled by same, in addition to communication between the accessories within the accessory module assembly 12 and the mirror assembly 14, may take a number of forms, for example using Bluetooth® technology, infrared (IR), or radiofrequency (RF) applications. Such wireless communication will simplify the wiring harness to be used within and to the accessory module system 10, and therefore also give greater flexibility to the system 10 in terms of the interchangeability of accessories that can be employed within the system 10. Hard wiring will still have to be employed to power the various accessories. However, the various wires could be replaced with a network of electrically conductive strips routed internally of the module assembly 12, with each branch or strip (not shown) being contacted by the respective accessory or a terminal thereof upon the location of the accessory within the frame assembly 16.

If the number of accessories contained within the accessory module assembly 12 is to be varied, it is preferable to provide a suitably modified cover assembly (not shown) to replace the cover assembly 18, which modified cover assembly can then be provided with the correct arrangement of apertures therein to correspond to the accessories being utilized. It will therefore be appreciated that the accessory module system 10 is modular in form and function.

As detailed above, due to the requirement for the rain sensor assembly 30 and the temperature sensor assembly 32 to be pressed against the windscreen with significant force, the frame assembly 16 is preferably formed from a substantially rigid material such as a metal or the like. For this reason, and as a result of manufacturing tolerances both in producing the accessory module system 10, and in producing the vehicle windscreen, the shape of the frame assembly 16 is unlikely to exactly match that of the curved windscreen of the vehicle, which may therefore result in slight gaps being present between the frame assembly 16 and the windscreen, negatively affecting the aesthetics of the accessory module system 10 when fitted. In addition, such gaps may allow the ingress of dirt/dust or the like contaminants between the windscreen and the module assembly 12, which may then obscure the vision of one or more of the accessories. For this reason, the cover assembly 18 is preferably formed from a resiliently deformable material, and is thus capable of deforming to conform substantially precisely to the shape of the windscreen, regardless of any slight deviations in dimensions due to manufacturing tolerances. Thus from the exterior of the vehicle the cover assembly 18 will provide the appearance of forming a perfect match between the accessory module assembly 12 and the vehicle windscreen, which should therefore prevent any dirt/dust from migrating between the windscreen and the module assembly 12. Although not illustrated in the preferred embodiment, it is also envisaged that the cover assembly 18 be resiliently or spring-mounted to the frame assembly 16, in order, in use, to actively urge the cover assembly 18 against the windscreen, in order to fully conform to the shape thereof.

The system 10 also preferably comprises the use of a frit (not shown) on the vehicle windscreen (not shown), at the position at which the accessory module assembly 12 is mounted. The frit should then be provided with clear areas corresponding in position and shape to the apertures and/or channels formed in the cover assembly 18.

Due to the position of the accessory module assembly 12 on the windscreen or other window of a vehicle, the accessory module assembly 12 will be subjected, in use, to significant incident radiation, in particular solar radiation, which could result in heating of the accessory module assembly 12, possibly adversely affecting the accessories contained therein. For this reason, the cover assembly 18 preferably comprises a heat deflecting material, more preferably a material having a heat deflection temperature of at least 75° C., more preferably at least 85° C., and most preferably at least 105° C.

In certain environmental conditions, it is possible that the area of windscreen effectively enclosed by the module assembly 12, and in particular by the various apertures in the cover assembly 18, may become misted/fogged, or otherwise obscured, thereby negatively affecting the performance of the various accessories in the system 10, which generally require a clear field of vision through the windscreen in order to perform effectively. In order to prevent such an occurrence, and referring to FIG. 6, the module assembly 12 is preferably provided with a first fluid impermeable gasket 80 surrounding the camera aperture 38 and associated channel 40, and a second fluid impermeable gasket 82 surrounding the transmitter aperture 46 and associated channel 48 and the receiver aperture 50 and associated channel 52. These gaskets 80, 82 form, in use, a seal with the windscreen to prevent the ingress of moisture and/or dirt into the spaces defined by the above mentioned channels 40, 48, 52, in order to prevent the formation/accumulation of mist/fog or dirt therein.

As a further measure, it is proposed that a respective vent or port (not shown) be provided, communicating with the otherwise sealed space or cavity defined by the gaskets 80, 82 and respective channels 40, 48, 52, said ports having a gas permeable but fluid impermeable barrier or membrane, in order to allow air into and out of the spaces, but to prevent moisture from reaching said spaces. Such a breathable membrane could be formed from Goretex® or the like.

In the absence of such a membrane, the air being channeled through the respective port could be directed over a relatively cool surface, for example the metal frame assembly 16, which would then cause a significant portion of any water vapor in the air to condense out onto the relatively cool surface, thus reducing or eliminating the occurrence of misting/fogging in said spaces. Alternatively the air may be channeled through a suitably designed baffle (not shown) which is adapted to permit the passage of heated air, but not any moisture contained therein, to reach the otherwise sealed spaces defined by the gaskets 80, 82. This ability to heat or otherwise control the environmental conditions within these spaces is particularly important when a vehicle is operating in cold climates, where frost may form on the outer surface of the vehicle windscreen. In order for the various accessories, in particular the camera 28 and CV sensor assembly 34, to have a clear view through the windscreen in order to operate correctly, the frost must first be cleared from the windscreen. This is normally achieved using heated air blown up and along the interior surface of the windscreen form the vehicles air conditioning system, which heats the windscreen through to the outer surface, thereby dispersing or melting the frost. However as a result of the gaskets 80, 82, this heated air cannot reach the areas of the windscreen through which the camera 28 and CV sensor assembly 34 look, and these areas must therefore be heated from within the module assembly 12 as described above.

It will of course be appreciated that any other measure may be taken to reduce or eliminate misting, fogging or frost on that portion of the windscreen against which the module assembly 12 is seated.

The accessory module assembly 12 can house a large array of sensor assemblies and other components, other than those describe in detail above, for example a cabin temperature sensor assembly, a cabin humidity sensor assembly, an ambient light and a glare sensor assembly for an electrochromic (EC) mirror cell, a phone system, petrol gauge display, and any other desired components or accessories. Many of these accessories were previously housed with a vehicles rearview mirror, and thus the provision of the accessory module assembly 12 can generate a relatively large amount of free space within the vehicles rearview mirror assembly. As a result, the mirror assembly 14 could be significantly reduced in size, in particular in depth or thickness, and especially where an EC cell is employed, thereby providing an aesthetically pleasing appearance. Alternatively or simultaneously, this additional space may be used to apply one or more digital displays to the rear of the EC cell, which can then display information, through the EC cell, to a driver or passenger of the vehicle.

It will thus be appreciated that the accessory module system 10 of the present invention provides a convenient location in which to house a large array of accessories and/or sensors or the like, and which is modular in terms of the combination of said accessories which may be housed within same.

The accessory module or system 10 of the present invention may utilize aspects of other accessory modules or windshield electronics modules or the like, such as modules of the types described in U.S. patent application Ser.
